Easy BCD: Bootable Partitions

This video shows how to set up bootable Windows partitions with Easy BCD.

Boot from Main and Backup Disk

• With Partition Wizard, one can copy an existing SSD
• Then we make it bootable offering different boot systems. Here we use EasyBCD.
• The so-created backup drive can be used when the SSD has issues
• Works well with Non-UEFI systems

EasyBCD Boot from Both Disk

Old Copies of Working Systems

We use EasyBCD for copies of working Windows systems, so that we can restore an earlier stage of the Windows system in addition to restore points.

In the screenshot, we see an older system.

Change Boot System: Partition Wizard

• Partition Wizard: Restore MBR one possibility
• Reboot without old boot disk
• use recovery or installation disk
• boot with recovery disk

Make Bootable

Via new master disk

Copy a master disk from another system or install a new operating system.
Windows 8 is preferred.
This master disk contains only a working OS.

It should boot via legacy and be MBR.

via Recovery Disk

• https://www.disk-partition.com/articles/cloned-hard-drive-ssd-wont-boot-4348.html
• Create recovery disk from running system
• Disconnect the running system disk
• Boot recovery disk
• accept changes from recovery disk
• boot again –> this time it boots MBR correctly
• choose one of the system that boots
• login with admin
• Map drives correctly (needed for right location script)
• run location script (some paths may be lost)

Boot from DVD

• Add keyboard cable during boot if keyboard is blinking
• Make ATAPI Default Boot in Bios
• or press F1/ESC during startup
• Disable UEFI

Make bootable via Windows Recovery

• Ensure that ATAPI is booted first —> BOot order in Bios
• Apply Repair During Boot
• Select Recovery System

• ] Windows Repair will add additional systems
• Bootup System Added

• and gives an overview of repair details
• Overview Boot Systems

GPT/MBR and UEFI versus Legacy

Boot loader:

The Windows boot loader on the HP Elite computer uses UEFI by default.
Advantages of UEFI are the boot from multiple systems.

EasyBCD that has problems with UEFI.

Disable UEFI.
Convert disks into MBR.

4. SSD not booting because of MBR error

(source)

Another reason for SSD not booting could be the MBR error. And you can try Bootrec.exe to fix SSD not booting after clone.

1. Boot from the repair disc, open Command Prompt.

2. Enter the following commands in order:

bootrec.exe

bootrec.exe /fixmbr

bootrec.exe /fixboot

bootrec.exe /scanos

bootrec.exe /rebuildbcd

If you do not have a repair disc, you can use AOMEI Partition Assistant to fix MBR error in a few simple steps.

Step 1. Using AOMEI Partition Assistant to create a bootable USB drive.

Step 2. Connect the bootable USB drive to your computer with the SSD installed and boot from the bootable USB drive.

Step 3. It will show you the main interface of AOMEI Partition Assistant. Here, right click the SSD, select Rebuild MBR.
